# = definition: bind::generate
#
# Creates a $GENERATE directive for a specific zone
#
# == Arguments
# $zone: mandatory - zone name. Must reflect a bind::zone resource
# $range: mandatory - range allocated to internal generate directive.
# Must be in the form 'first-last', like '2-254'
# $record_type: mandatory - must be one of PTR, CNAME, DNAME, A, AAAA and NS
# $lhs: mandatory - generated name (see examples)
# $rhs: mandatory - record target (see examples)
# $record_class: optional - incompatible with pre-9.3 bind versions
# $ttl: optional - time tolive for generated records
#
# == Examples
#
# bind::zone {'test.tld':
# zone_contact => 'contact.test.tld',
# zone_ns => 'ns0.test.tld',
# zone_serial => '2012112901',
# zone_ttl => '604800',
# zone_origin => 'test.tld',
# }
# ## Generate A records
# bind::generate {'a-records':
# zone => 'test.tld',
# range => '2-100',
# record_type => 'A',
# lhs => 'dhcp-$', # creates dhcp-2.test.tld, dhcp-3.test.tld …
# rhs => '10.10.0.$', # creates IP 10.10.0.2, 10.10.0.3 …
# }
# ## Means: dig dhcp-10.test.tld will resolv to 10.10.0.10
#
# ## Generate CNAME records
# bind::generate {'a-records':
# zone => 'test.tld',
# range => '2-100',
# record_type => 'CNAME',
# lhs => 'dhcp-$', # creates dhcp-2.test.tld, dhcp-3.test.tld …
# rhs => 'dhcp$', # creates IP dhcp2.test.tld, dhcp3.test.tld …
# }
# ## Means: dig dhcp10.test.tld => dhcp-10.test.tld => 10.10.0.10
#
# bind::zone {'0.10.10.IN-ADDR.ARPA':
# zone_contact => 'contact.test.tld',
# zone_ns => 'ns0.test.tld',
# zone_serial => '2012112901',
# zone_ttl => '604800',
# zone_origin => '0.10.10.IN-ADDR.ARPA',
# }
# ## Generates PTR
# bind::generate {'ptr-records':
# zone => '0.10.10.IN-ADDR.ARPA',
# range => '2-100',
# record_type => 'PTR',
# lhs => '$.0.10.10.IN-ADDR.ARPA.', # 2.0.10.10.IN-ADDR.ARPA …
# rhs => 'dhcp-$.test.tld.', # creates dhcp-2.test.tld …
# }
# ## Means: dig 10.10.0.10 will resolv to dhcp-10.test.tld
#
#
# For more information regarding this directive
# and the definition arguments, please have a
# look at
# http://www.bind9.net/manual/bind/9.3.2/Bv9ARM.ch06.html#id2566761
#
# NOTE: in order to prevent some funky-funny thing, the orignal
# "class" and "type" variables
# are renamed as $record_class and $record_type in this definition.
